INVENTOR PROCESS OF AND APPARATUS FOR WAXING THREADS.

Specification of Letters latent.

Patented June 19, 191?.

Application filed January 10, 1916. Serial No. 71,251.

To all whom it may concern:

Be it known that I, J OSEPH Fnnnnmo HOUSTON, a citizen of the UnitedStates, residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Process of and Apparatusfor Waxing Threads, of which the following is a specification.

My invention relates to the art of waxing threads or yarn, and itsobject is to -thor-. oughly coat with wax the exterior of a completedthread and to wind it in its waxed condition upon a cone, spool, bobbinor kindred tubular or other carrier.

A further object of my invention is to so apply the thread to the waxthat its surface shall be evenly coated and unnecessary waste of waxavoided.

My invention, broadly considered, comprehends an apparatus foraccomplishing the foregoing result a typical embodiment of which isillustrated in the accompanying drawings and hereinafter described, andalso a process which may be conveniently carriedv out by the utilizationof the apparatus referred to or of one of generally equivalent type.

For the purpose of illustrating my invention, I have shown in theaccompanying drawings a certain type and embodiment of it which is atpresent preferred by me, since in practice it gives satisfactory andreliable results. It is to be understood, however, that the variousinstrumentalities in which my invention is embodied can be variouslyarranged and organized and that my invention is not therefore limited tothe precise arrangement and organization of the devices typified in theconstruction represented in the accompanying drawings and hereinafterdescribed.

In the drawings,

Figure 1 represents in side elevation an apparatus convenientlyembodying my improvements so far as they are concerned with apparatus,and well adapted for the practice of my process.

Fig. 2 represents in perspective one of the wax-carrying cones of whichI make use.

Fig. 3 represents a cone in central, vertical, sectional elevation,illustrating in place the core or mold of wax or other waxing mediumwhich it contains.

Fig. 4 represents a top plan, sectionally on the dotted lines m-m ofFig. 2, of the wax carrying cone with the wax core removed.

Fig. 5 represents in perspective the core or "inserted.

Fig. 7 represents in fragmentary perspective a portion of thewax-carrying cone and of the core of wax.

Similar numerals of reference indicate corresponding parts.

Referring to the drawings 1 designates a carrying and supportingframework of any preferred character,'referably to which the componentelements of my apparatus are mounted and sustained.

Uponthe base plate 2 of'the framework are mounted a plurality ofbobbins, cops, spools or thread carriers 3, of any desired character,upon which the thread to be waxed is wound. For convenience of description I designate these devices as primary bobbins.

I designates the threads upon the primary bobbins which are to be waxed.

5 designates a plurality of hollow wax carrying cones or wax containers,which, in the organization under discussion, are fastened base downwardupon a cone-carrying bar 6, being a part of the framework.

The cones 5 are, as stated, hollow and are made of any material,butpreferably as a casting of glass,and each is formed with a verticalslot'extending from its base to its apex, which as to one of its sidesis formed or provided with what I term a lip or flange 8, outwardlyextending and preferably wide at the base and vanishing at the apex ofthe cone. The function of this flange is to serve as a guide for theinitial throw or introduc tion of the thread within the hollow interiorof the cone.

9 designates lugs of any desired number, preferably two, which are castto extend radially outward from the baseof the cone so as to serve asholding devices through which screws or bolts 10 may pass to secure thecones to their carrying bar 6. These lugs are simply devices ofconvenience, and their e uivalent would be a circumferential outwarly-extending basal web by means of holes in which attachment of thecones may be secured.

11 designates an internal basal flange within the cone, the function ofwhich is to retain the core of wax when in place within the cone againstthe possibility of dropping out.

12 designates internal, vertically-extending ribs formed or appliedwithin the carrying-cone, the function of which is to retain the core ofwax against possible circumferential displacement.

13 designates a hollow core or body of wax or equivalent material,preferably cast within the carrying cone and serving as a lining to it,against the conical internal hollow surface of which the thread in itspassage through the core and cone in the practice of my'process, isballooned or centrifugally thrown into contact. The core is slotted at 11 to correspond with the slot 7 in the cone.

It being of the essence of the construction that the cone should belined with wax, it is immaterial Whether the wax in a molten conditionbe poured into the cone,-of course against some temporary core as in anymolding operation,or whether it be cast as an entirety and forced intoplace in the carrying cone.

Obviously, however, if the latter method be resorted to, the basalflange 11 would'not be necessary. I prefer to cast the wax core withinthe cone.

15 designates a plurality of very rapidly rotated driving rolls each ofwhich serves to draw a thread with regard to which it operates, upwardlyoff its basal bobbin i. and through its Wax-carrying cones 5, in amanner well understood in the operation of winding machines for conesand tubes, and so to permit of the feeding and wrapping of said threadupon a cone carrier 16 which is typical merely of any type of carryingand receiving spool, bobbin, tube or beam, which 'serves as the ultimatecarrier for the waxedand finished thread.

The driving rolls are shown as mounted upon a driving shaft 17 mountedinwthe framework, and guide or feed rolls which cooperate with saiddriving rolls are shown and designated 18.

19 designate traverses of; the type generally embodied in cone and tubewinders, shown as mounted upon a traversebar 20, and to which areassumed to be imparted their usual movement of longitudinalreciprocation relativeto the cone carriers, by any usual means, notnecessary to illustrate.

Such being a descri tion of an apparatus which I find it convenient toemploy, its operation which involves the practice of; my process will beeasily understood? Assuming vthe primary bobbins,+-and a plurality ofthem is of course "supposedsupplied with finished thread to be waxed Thethread will thenbe inserted into the wax-carrying cones through theslots in the cones and cores, which the lip or flange of the conerenders easy,--and will be then carried up through the hollow interiorsof the carrying cones, passing through the traverses, and will beconnected with the ultimate carriers.

The driving shaft will then be set in action to occasion the very rapidrotation of said ultimate carriers,and the thread will be drawnup-through the wax core of the carriers, and in its passage or act ofbeing drawn up, will be, to use the technical expression, ballooned orthrown out centrifugally to cause it to be, so to speak, whipped againstthe waxed surface, with the result that in the very rapid combinedmovement of longitudinal passage through the waxed core and rotarywhip-' p s or ballooning against its surfaces, the thread will beuniformly and thoroughly coated withwax.

The typical representation of Fig. 1 of the drawing indicates theoutward throw or outwardly curved position which the thread 4 in itspassage between the primary bobbin and the wax-carrying cones is causedto assume,the dotted lines opposite the full lines generally indicatingthe so-called ballooning shape imparted to the thread in its travel.

This ballooning is due entirely to the conjoint action of the rapidlyrevolving cone-carriers 16,which, as explained, serve as the ultimatecarriers for the waxed and finished threads,in the drawing off orunwinding of the thread frtin the primary bobbins,and is anecessaryconcomitant of the twoactions.

It is,'moreover, to be understood that the apparatus as an entirety maybe disposed in other than a vertically-operating, position, although inall machines of this general character it is usual and most advantageousto lead the threads upwardly rather than laterally or downwardly.

It will now be apparent that I have de vised and explained an apparatuswhich embodies the features of advantage referred to as desirable andwhich is well adapted for the practice of my process. I wish it,however, to be understood that the apparatus may be materially modifiedin various details without departing from the spirit or scope of theinvention or sacrificing any of its advantages.

Having thus described my invention, what I claim as "new and desire tosecure by Letters Patent, is
